Temporary rules adopted by London’s Richmond Golf Club during the Battle of Britain:

I had my doubts about this, but the rules are acknowledged by the club itself. While we’re at it: In A Wodehouse Handbook, N.T.P. Murphy notes two unusual tournament rules at the annual Bering Sea Ice Classic in Nome, Alaska:

• If a player hits a polar bear, he is penalized three strokes.
• If a player hits a polar bear and retrieves his ball, he is awarded five strokes.

Apparently those are local rules: In Extreme Golf, Duncan Lennard notes that officials of the World Ice Golf Championship actually wrote to the game’s governing body, the Royal and Ancient Golf Club of St Andrews, to ask what to do about polar bears, and received the ruling that “in the event of a polar bear wandering onto the ice golf course, the same safety procedure should be followed as for rattlesnakes and ants elsewhere in the world” — a free drop out of harm’s way.
